I think what you are really looking for is a device which can carry water 5 metres without mechanical assistance? Anyway, I will answer the question based on that assumption.

There are relatively strong cohesive forces between water and glass, which is why there is a concave meniscus where water meets the sides of a glass tube. If you have an extremely thin tube (by thin I mean the inner diameter, not the wall thickness, then water is drawn along the tube quite a long way. 5 metres is not an impossible task, even against the force of gravity. In fact, if you rephrased the question to ask how to carry water in a weightless environment, my answer will provide one solution!

If you're really all that (please)^n about it, you might consider telling your breathless audience what in heck you're talking about. Carry water where? Up? Down? On wheels? With human or engine power added or all by itself?
BTW, the capillary device will only work once. It will fill with water, then it will take energy to move that water out so more water can replace it. It won't continuously transport the water unless we use gravity and the transport is in a downward direction. I hope the asker wasn't expecting perpetual motion.
Anyway, without knowing enough about the problem, I'll suggest boiling the water and piping the steam to a cold place where it will condense. Not efficient, but you didn't say it had to be.
